Technical Bulletins

Technical Bulletins provide guidance concerning the specific code interpretations used by the Building Division of Permit Sonoma. They are intended to aid members of the development community, such as design professionals, builders, and others complying with the codes adopted by Sonoma County.

Each bulletin contains an introduction, specific technical details, and illustrations relating to each topic as appropriate. References are provided to the current California state codes, Energy Efficiency standards, Federal and State legislation, and Sonoma County Codes and Ordinances. New bulletins, as well as updates of existing bulletins, are issued periodically.

There are some duplicate Technical Bulletins due to building code changes that became effective January 1, 2008. The version including an "X" in the title is to be used only for construction projects that were submitted prior to January 1, 2008.

Comments on the Technical Bulletin series can be directed via email to Nathan Quarles.
